Of this, 76 percent will be for single-aisle aircraft like the Boeing 737 and Airbus (AIR.PA) A320, said Dinesh Keskar, senior vice-president for Asia Pacific and India sales at Boeing.

This will be largely driven by low-cost carriers, and the growth of markets such as Indonesia, Myanmar and Vietnam, he added.

Southeast Asian passenger traffic has grown by more than 9 percent since 2010, with intra-Southeast Asian traffic projected to increase by 7.7 percent over the next 20 years, said Keskar.

“The total pie and the number of people traveling is still very low,” he added.

The Asia Pacific region as a whole will absorb 14,550 aircraft, more than a third of the 39,050 aircraft that are required globally, according to Boeing’s forecast.

IATA director general Tony Tyler said on Sunday that record plane orders placed by ambitious Southeast Asian airlines could be at risk in an environment of intense competition, low profitability and turmoil in financial markets.

Fast growing low-cost carriers such as Indonesia’s Lion Air, Malaysia’s AirAsia (AIRA.KL) and India’s IndiGo have ordered hundreds of Airbus and Boeing jets over the last decade in a bid to secure market share.

Lion is the only Boeing customer of those three, and Keskar said that the airline had been taking all of its ordered 737s. Boeing, he added, was in a “good spot” and had not had requests for deferrals from any of its other customers.

“Most of our customers have been ordering 25, 30, 40 aircraft at a time and then replacing them every three to four years,” said Keskar, who added that the steady growth plans help these airlines.
